Area Forecast Discussion
National Weather Service Mobile AL
126 PM CDT Sat Apr 16 2022

.NEAR TERM /Now Through This Evening/...A zonal to northwesterly flow
aloft is in place as an upper-level trough digs into the Great Lakes
region and a ridge builds over Mexico. With these two features
interacting, jet stream flow at the 300mb level has split over
Eastern Arkansas and Western Mississippi, with a northwesterly jet
situated over Louisiana/Southern Mississippi and a westerly jet over
the Ohio River valley. Embedded shortwave energy will also be moving
through the flow aloft, helping to induce lift across the region.
Looking in the lower levels, a surface frontal boundary is currently
draped from northwest Mississippi into southeast Alabama. This
boundary will slowly sag southward throughout the day today, before
stalling over our region this evening and lifting back to the north
Sunday morning.

Current analysis shows strong differential divergence over Eastern
Arkansas/Western Mississippi, where a portion of the surface
boundary resides, a 500mb shortwave trough is located, and the
aforementioned 300mb jet split took place. This has resulted in
ongoing showers and thunderstorms across that region. Looking east,
a 30-40 knot 850mb low level jet, which was over Eastern Alabama
earlier this morning, has departed, leaving behind a much weaker 20-
25 knot flow over the region. This likely assisted in the early
morning storm development over Central Alabama, which has since
waned as they entered our northern CWA counties. Additionally,
sufficient low-level moisture and instability has returned, with dew
points across the region in the upper 60s to near 70 and
temperatures (outside of regions that already received rain this
morning) in the low 80s, giving way to steep low-level lapse rates
and MLCAPEs of 1500 to 2000 J/kg. Although PWATs are between 1.4
to 1.7 inches, a rather stout dry layer was present above 700mb
in the 12z soundings from KLIX and KJAN. With northwesterly flow
aloft in place, this dry layer will have likely advected into our
region, bringing with it estimated DCAPEs of around 800 to 1000
J/kg.

As the frontal boundary pushes southward and the shortwave moves
within the northwesterly flow aloft, the region of maximized
differential divergence will push into our local area. With
sufficient moisture and instability in place, along with bulk shear
values around 30 to 35 kts, expect the shower and thunderstorm
activity to intensify as it pushes southeastward, likely reaching
our region by mid to late afternoon. High DCAPE values suggest that
storms have the potential to produce damaging downburst winds gusts
up to 60mph. Additionally, the dry air aloft and high instability
values suggest a hail threat (up to quarter-sized)with some of the
stronger storms. Storms will begin to weaken and rain coverage will
decrease by the late evening hours as instability values drop due to
the loss of daytime heating and the shortwave trough exits the
region. /96

&&

.AVIATION...
18Z issuance...VFR conditions are currently present across much of
the region. By mid to late afternoon, showers and thunderstorms,
some of which could produce damaging winds and hail, will spread
across the region. A lowering of visibilities and ceilings may occur
in some of the heavier storms. Rain coverage will decrease by the
late evening hours. By early Sunday morning, low stratus will move
into the region, possibly lowering ceilings to IFR. Additionally,
some patchy fog may also develop, reducing visibilities. Fog will
dissipate by mid-morning and ceilings should lift to MVFR by
Saturday afternoon before the next round of showers and storms
approach the region. /96
